Speech is very colloquial. Living in Texas, I'd have to write off about 90% of the people I know if I judged them by poor grammar of speech. The fact of the matter is that most of the 90% I'd be writing off are actually educated, intelligent, wonderful people who just happen to like to use Texas-speak. In fact, I'm as guilty as anyone in lapsing into Texas twang (which is more than just an accent). Very few people actually speak in 100% grammatical English; sounds like you have an issue that could eliminate almost everyone you encounter if that is your standard for choosing companionship. Might need to lose that one.
